Scalability is a hot topic in tech, and every programming language or framework provides its own way of handling high loads of traffic.

Today, we’re going to see an easy and straightforward example about Node.js clustering. This is a programming technique which will help you parallelize your code and speed up performance.

“A single instance of Node.js runs in a single thread. To take advantage of multi-core systems, the user will sometimes want to launch a cluster of Node.js processes to handle the load.”- Node.js Documentation

We’re gonna create a simple web server using Koa, which is really similar to

Create React App 2.0 has been released today, and it brings a year’s worth of improvements in a single dependency update.

While React itself doesn’t require any build dependencies, it can be challenging to write a complex app without a fast test runner, a production minifier, and a modular codebase. Since the very first release, the goal of Create React App has been to help you focus on what matters the most — your application code — and to handle build and testing setup for you.

Many of the tools it relies on have since released new versions containing new features and performance improvements:

Practical Suggestions To Improve Usability Of Landing Pages With Animation From Slides

Good functional animation makes a landing page not just more appealing, but also more usable. When done correctly, animation can turn a landing page from a sequence of sections into a carefully choreographed, memorable experience. Meet Slides, a framework that will help you use animation to communicate clearly.

Recently, I created a project management tool called enamel. It’s now used by my employer, and hopefully I can sell it to more customers.

In this tutorial series, we are going to build this app from scratch:

Part 1 — building a simple GraphQL API (this part)

Teaching how to build my own product sounds a bit weird. By the end of the tutorial, you will know how to build my product and so you can become my competitor. But building a business is much more than a product. So I’m not worried about that at all. You can use the code however you want.

The reason I’m doing this is that I learned so much and had fun along the way and I want to share with you my experience.

Consider all the software that you use in your life. It doesn’t matter if you’re a developer or a regular user that just casually browses the internet and checks up on social networks. Almost all software that you can identify uses some form of API.

APIs (application programming interfaces) enable software applications to communicate with other pieces of software consistently. Either internally to connect to a component of the application or externally to connect to a service.

Using API-based components and services in development is also a great way of maintaining scalability and productivity as it enables you to develop multiple applications based off of modular and reusable components, allowing scalability and facilitating maintenance.

Load your own samples Create your own custom wavetables based on samples. Just drag and drop your favorite pre-recorded synth, drum sound, vocal or even a loop to start exploring it’s hidden capabilities as new synth material or even as a filter.

This marks the next step in our journey to drive innovation across every facet of commerce.

As Content + Commerce capabilities have become inextricably linked, commerce plays a more integral part of the consumer experience than ever before.

With Magento’s position as the world’s most popular commerce platform and Adobe’s leadership in designing and delivering great digital experiences, we will enable every business to create and deliver compelling real-time experiences, engage with customers across every touchpoint, and transact anywhere across the entire customer journey for both B2C and B2B.

So, there I was. A front-end developer who loves a good challenge. I was determined to turn an image into an elegant piece of code. And I also wanted to animate it. You see, for me, there is nothing more challenging than going deep into CSS and HTML, and honing these skills. Therefore, I’m always on the lookout for something that will push me and also allow me to evaluate where I can improve.

Before I found this challenge and as part of my self-improvement journey, I tried to play with the Daily CSS Images, but sadly I don’t have much time to do it! Another thing I do regularly is create small snippets of CSS interactions based on Dribbble Shots.

Many of today’s discussions around blockchain technology remind me of the classic Shimmer Floor Wax skit. According to Dan Aykroyd, Shimmer is a dessert topping. Gilda Radner claims that it is a floor wax, and Chevy Chase settles the debate and reveals that it actually is both! Some of the people that I talk to see blockchains as the foundation of a new monetary system and a way to facilitate international payments. Others see blockchains as a distributed ledger and immutable data source that can be applied to logistics, supply chain, land registration, crowdfunding, and other use cases. Either way, it is clear that there are a lot of intriguing possibilities and we are working to help our customers use this technology more effectively.

Wonderful, friendly people who keep this lil' site alive — and get smarter every day.

Service Worker is probably one of the most misrepresented technologies we currently have. When I hear people talking about it, the topic almost always revolves around serving an app when a user is offline. However, Service Worker can do so much more than that, and every week I come across new articles that show how powerful the technology really is.

Components are the basic building blocks of any Angular project. In this article we will cover some advanced topics about the components, such as how to create dynamic components and also how to create some advanced components in Angular projects. First of all we will learn how to create dynamic components in Angular projects.

Let’s assume that I have two component, “firstComponent” and “secondComponent”. Following is the content of both components.

Vertical Rhythm is an important concept in web design. It has the ability to bring a design together and make different elements feel consistent on the same page.

It was impossible to change Vertical Rhythm at different viewports previously, because we didn’t have the right tools. But now, with CSS Calc and CSS Custom Properties, we can change Vertical Rhythm at different viewports. This article explains how.

Calculating the rhythm unit

A rhythm unit is the base multiple you’d use for the Vertical Rhythm of your site. The value of a rhythm unit should be the line-height of your body text.

I’d probably assume that most of us started in UI design with the littlest knowledge or nothing at all. But even though the odds were against us at the start, we managed our way through numerous design books and articles to understand how colors, typography, layout etc works.

Thus in this article, I’ll be sharing a list of things I’ve learned from different designers, things I’ve learned in designing user interfaces, and new discoveries I found along the way:

*Disclaimer: The following “Don’t” samples provided doesn’t necessarily mean they’re wrong. It’s our basis of how we can improve from a good design solution to a much better one

Disclaimer: chiccocoin is not a true cryptocurrency and we do not sell it , this article is for recreational / educational purposes only

Every day on our feeds we find news about new cryptocurrency or someone who says that they are a big bubble that will soon explode and of which only the blockchain will remain. But, what is the blockchain?

By definition:

Is a continuously growing list of records, called blocks, which are linked and secured using cryptography.

So, the blockchain is an immutable, sequential chain of records called Blocks. Each block can contain transactions, files or any data you like. The important thing is that they’re

We’re very excited to announce the stable release of Rekit Studio, a complete IDE for React, Redux and React Router development! Though it’s maybe new to some of you, it has helped us build complicated web apps for more than one year.

The previous version of Rekit Studio was Rekit Portal, which has no ability to edit code. Now thanks to Monaco Editor which also powers VS Code, and prettier, an amazing tool for formatting code, Rekit Studio provides great experience for coding. That’s also why we renamed it from ‘portal’ to ‘studio’.

As an IDE, besides code editing, Rekit Studio provides the capability of code generation, dependency diagram, refactoring, build, unit tests and a meaningful way of code navigation. You will no longer care about how to setup the project, config webpack or organize folder structure. Rekit Studio provides an integrated way to manage the project. That’s what makes Rekit Studio different from other code editors like Sublime Text, VS Code.

Frontend web development has never been a hotter or more controversial topic.

Where once it was the server-side community that was embroiled in arguments over seemingly obscure topics, like whether ORMs were useful abstractions, now you can’t ask whether CSS belongs in JavaScript without raising everyone’s hackles.

The proliferation of frameworks and buzzwords in the JavaScript ecosystem has gotten so extreme that Medium thought pieces on JavaScript fatigue are the new lightning rod of the development world. We can’t even stare at our own navels without sparking off a ‘navel-gazing considered harmful’ trend on hackernews.

Our mission at Tutorialzine is to keep you up to date with the latest and coolest trends in web development. That’s why every month we release a handpicked collection of some of the best resources that we’ve stumbled upon and deemed worthy of your attention.

With ClarifyJS you can easily create chained methods that can be executed in any order you want. Usually javascript methods are executed from left-to-right, ClarifyJS allows changing the order in which they are executed. It also allows controlling async methods by choosing whether the process should wait for a specific async method to complete or just execute and move on.

Almost any website you visit today is protected by HTTPS. If yours isn’t yet, it should be. Securing your server with HTTPS also means that you can’t send requests to this server from one that isn’t protected by HTTPS. This poses a problem for developers who use a local development environment because all of them run on http://localhost out-of-the-box.

At the startup I’m a part of, we decided to secure our AWS Elastic Load Balancer endpoints with HTTPS as part of a move to enhance security. I ran into a situation where my local development environment’s requests to the server started getting rejected.

The function mutate changes the object it gets passed as a parameter. In a “call by value” environment, the function would get passed the value — so a copy — that the function could work with. Any changes the function makes to the object would not be visible outside of that function. But in a “call by reference” environment like JavaScript, the function gets a — you guessed it —

This concepts are very used nowadays on functional programing, but because of the heavy mathematical background, sometimes it may be confusing to understand all the definitions.

In this post I’ll try to clear a little more the understatement of this subject, but not going too deep and using simple examples, helping you to create your own functors and monads. I wish you enjoy it!

Following the mathematical definition, and relating in the programing world in a very simple way, functors are a mapping using a function f(x) (or composite function f(g(x)) for instance) on a category A generating a category B,

There are a few concepts in CSS layout that can really enhance your CSS game once you understand them. This article is about the Block Formatting Context (BFC). You may never have heard of this term, but if you have ever made a layout with CSS, you probably know what it is. Understanding what a BFC is, why it works, and how to create one is useful and can help you to understand how layout works in CSS.

In this article, I’ll explain what a BFC is through examples which are likely to be familiar to you. I’ll then show you a new value of display, that really only makes sense once you understand what a BFC is and why you might need one.

For you to be reading this, it surely would be no news that data visualization has become a very critical part of the IT world today. The huge amount of data being generated by different web technologies need to be properly refined and visualized for the world to use and gain insights from.

The advantages of understanding data are tremendous and it leads to taking well-informed decisions over time. The ability of an organization to get their data extracted, cleaned, visualized and analyzed could very much be the difference between profit or loss.

As a front-end web developer, it is a great skill set to be able to visualize data as much as you can make beautiful interactive web pages. These JavaScript libraries have made the task easier, as developers do not have to endure a change of language syntax to convert those magical numbers into understandable charts.

Creating a New Project

Once you’ve signed up for Dropsource, you would create a project. You can choose either iOS or Android. After that, you’ll see the editor’s main screen. Create the initial structure in a few clicks. Each screen in your app is represented as a page, and your app needs to have at least one page in it. So, the first thing we need to do is select the “Pages” option on the left of the editor.

The first page you create will be automatically set as the home (or landing) page for your app. This is the page your users will see first. You can also respond to page lifecycle events (such as “Page Loading,” “Page Appearing,” etc.) in the “Events” tab. For example, by changing “Page Loading” events, you can add a loading animation during the data-loading process.
